Enough to dedicate an 60-90mins of my day to scalping one or two trades and then go about my day as usual. I have a consistent strategy I backtested and follow. I don't see a trade that meets my criteria, then I close my broker. Most people that day trade don't do that and that's why they lose money.

I've been trading for a while and don't suggest to others to trade futures[0]. It's essentially highly leveraged stock, but less risk than options.
